1 Claim. 1

This invention has relation to an air conditioning device.

An object of the invention is to provide an air conditioning device which will be of new and improved construction.

A further object is to provide an air condition device devised to be especially useful for the purpose of employment within the interior space of automotive vehicles and incorporating desirable and improved features and characteristics.

And a further object is to provide an air conditioning device of construction and operative in the manner as hereinafter set forth.

With the above objects in view, as well as others which will appear as the specification proceeds, the invention comprises the construction, arrangement and combination of parts as now to be fully described and as hereinafter to be specifically claimed, it being understood that the disclosure herein is, merely illustrative and intended in no way in a limiting sense, changes in details of construction and arrangement of parts being permissible as long as within the spirit of the invention and the scope of the claim which follows.

In the accompanying drawing forming a part of this specification,

Fig. 1 is a side elevational view of an air conditioning device made according to the invention;

Fig. 2 is a top plan view of the air conditioning device;

Fig. 3 is a central longitudinal sectional view, taken on line 33 in Fig. 2; and

Fig. 4 is a central longitudinal sectional view, taken on line 4-4 in Fig. 1.

A housing Ill of the air conditioning device is of curvilinear configuration in the disclosure as made.

A partition II within and across the housing Ill provides a relatively small, first chamber I2 within said housing at one side of said partition and a comparatively large, second chamber I3 within the housing at the side of the partition opposite the first chamber I2; Said partition II is cut away at one side thereof to provide a communi-cating passageway I4 between said first and second chambers I2 and I3. The communicating passageway I4 is contiguous with a wall of the housing l6, and the partition II separates and isolates the first and second chambers I2 and I3 from each other save by way of said communicating passageway I4.

An electric motor I5, within the first chamber I2 and suitably and conveniently supported, as at I6, upon the partition II, is adapted to be energized by electrical energy from any suitable source (not shown), and a blower II fixed upon the shaft of the electric motor I5 is for forcing air out of said first chamber I2, through the communicating passageway I4 into the second chamber I 3 and out of said second chamber. The electric motor I 5 and the blower I! are in spaced relation to said communicatin passageway I4, and the construction and arrangement are such that said blower forces air toward said communicating passageway.

The housing I 0 includes an openable door I8, contiguous with the first chamber I2 and at the side of the electric motor and blower opposite the communicating passageway I4, for afiording access to said electric motor and blower, and air inlet passageways through said door to said first chamber I2 are denoted I9. Said first chamber I2 is closed save for said openings I9 and communicating passageway I4.

The second chamber I3 contains a restilinear support 20 for a slidable drawer 2I adapted to receive a cooling medium, such, for example, as Dry Ice or ordinary ice. The rectilinear support 20 may be assembled with the housing I 0 in any suitable and convenient manner. As disclosed, said rectilinear support is constituted as a bottom wall 22, an interior end wall 23 extending upwardly from said bottom wall and spaced apart, parallel side walls 24, 24, and the rectilinear support is open at its upper side and exterior end. The bottom wall 22 of said rectilinear support slants downwardly from its exterior portion to an intermediate part of said bottom wall and opens to a drain pipe 25 leading from the bottom wall, and the open, exterior end of the rectilinear support 20 is contiguous with an opening through a wall of the housing I 9 situated at a side of said housing opposite and below the openable door I8. The drain pipe 25 leads to a bottom wall of the housing II] by way of a transverse wall 26, and said bottom wall normally is closed by a spring pressed plug 21.

The slidable drawer 2I rests upon the bottom wall 22 of the rectilinear support 20 andspans the distance between the side walls 24, 24 to be slidable inwardly and outwardly of the housing I0 and said rectilinear support. Said drawer 2I includes a base wall 28 having perforations 29, an interior end wall 30 extending upwardly from said base wall, an exterior end wall 3| extending upwardly from the base wall, and spaced apart, parallel side walls 32, 32 connecting the interior and exterior end walls 30 and 3|. The perforations 29 are for passage of water to the drain pipe 25 when ordinary ice is the cooling medium em- 3 ployed. The slidable drawer BI is open at its upper side, and the construction and arrangement will be such that the second chamber is will be closed at the location of the open, exterior end of the rectilinear support 28 and the exterior end wall 35 of the slidable drawer 2| when said slidable drawer is in its closed position as in Fig. 3 of the drawing. Stated differently, said exterior end wall 3i includes extension portions at its up per, lower and opposite sides adapted to seal the second chamber it closed when the slidable drawer ii is in shut condition.

The slidable drawer 2! is in somewhat spaced relation to the partition i i, and in parallel relation to said partition in the disclosure as made. The interior end walls and spaced apart side walls of the rectilinear support and slidable drawer are in spaced relation to the bounding side walls of the housing iii, and the bottom wall 22 of said rectilinear support is in spaced relation to the transverse wall 26 of said housing. Upper extension portions 53, 33 upon the spaced apart side walls 24, 2 2 of the rectilinear support 2:? are contiguous with the adjacent surface of the partition i and with opposite side walls of the housing It, and lower extension portions 3-2, 3 upon said spaced apart side walls 24, 2d are contiguous with the adjacent surface of said. transverse wall 2% and also with opposite side walls of said housing. Thus is provided an air channelway from the communicating passageway is extending over the top or the slidable drawer 2i, along the inner side of the interior end wall 23 of the rectilinear support 2% and under the bottom wall or" said rectilinear support, said air channelway being bounded at its upper portion by said partition l i, at its lower portion by the transverse wall 26, at its opposite sides by the upper and lower extension portions 3 3, 33 and 3 3d, and at its intermediate portion by a wall of the housing iii adjacent the interior end wall As. The communicating passageway M is entirely within the confines of the air channelway, and outlet passageways from said air channelway through a wall of the housing iii and within the confines of said air channelway, are denoted Said outlet passageways 35 are at the side of the sldable drawer 2! opposte tl e communicating passageway I l, directly beneath said communicating passageway, in the disclosure as made.

A curvilinear deflector in the air channelway beneath the communicating passageway l i is for directing air traveling from the first chamber l2 into the inlet end of the air channelway to pass along the part of said air channelway over and contiguous with cooling medium in the slidable drawer H to the intermediate portion of the air channelway.

A bracket 32" is for supporting the air conditioning device upon a structure, such, for example, as the dash of an automotive vehicle, and a hand piece 33 upon the exterior end wall 3! of the slidable drawer 25 is for ready manipulation of said slidable drawer.

The manner in which the air conditioning device functions will be apparent. When the blower H is in operation, air will be drawn into the first chamber i2 by Way of the air inlet passageways i9 through the openable door I8, and the drawn in air will be forced out of said first chamber l2 through the communicating passageway I4 and made to travel along the air channelway, first over the open, upper side of cooling medium in the slidable drawer 2|, then along the inner side of the rectilinear support 20, and finally along and under the bottom wall 22 of said rectilinear support. The forced air will pass out of said air channelway and out of the housing it through the outlet passageways 35. It will be apparent that air forced through the air channelway will travel along the upper, interior and lower sides of the cooling medium thus to be capable of giving up its heat to the maximum extent possible.

When cooling medium in the slidable drawer 21 becomes spent, said slidable drawer can be removed, replenished with COOliIlg medium and replaced.

What is claimed is:

A portable air conditioning device comprisin a housing, first and second horizontal partitions within and across said housing providing therewith a first chamber above said first partition, a second chamber below said first partition and above said second partition and a third chamber below said second partition, said first chamber being open to atmosphere by way of an inlet to said housing and there being a communicating opening in said first partition between the first and second chambers adjacent the wall of the housing opposite said inlet, said first chamber being closed save for said inlet and communicating opening, a container in said second chamber spaced from said first and second partitions, a drawer for ice slidably supported by said container accessible at an outer side of said housing and having a perforated lower wall, said housing, first partition and container providing an air channelway contiguous with said communicating opening and extending across the top, one of the sides and the bottom of said container, said air channelway being closed when said drawer is in inserted position save for said communicating opening, and an outlet from a lower portion of the air channelway below said container, a funnel shape drain constituted at the bottom wall of said container, a drain pipe leading from said funnel shape drain to a point inside said third chamber, said housing being provided with a drain hole at a lower portion of said third chamher, a drain plug normally closing said drain hole accessible from an outer side of said housing and adapted to be manually actuated to open position with respect to said drain hole, a blower for forcing air through said channelway mounted on said first horizontal partition in said first chamber, and an external supporting bracket integral with said housing for securing said device to a wall.
